Bluetooth afraid of interference signals?

Users questions:I and my brother often chat with Bluetooth mobile phones. Were to die today, with the use. Yeah we all use Nokia's 7610. Chat software with fresh color sensors. No problem with straight, only a wall away from the grounds. Before every day. Is not afraid of interference?
Experts answer: Bluetooth work in the 2400-2483.5MHz frequency band, and most of the wireless LAN is in a band. Wireless local area network may be somewhere in the interference. But this probability is small, because there is a frequency hopping Bluetooth technology, this frequency band depending on whether there is a conflict to take up to 79 times the frequency. Look around there are no proposed wirelessLAN, there is the theory, although Bluetooth can be through one or two walls, but try not to repeat it, this would seriously weaken the signal more vulnerable to interference. Try Bluetooth connection is usually also have no problem, if so, it could be a question of the machine.
